   <fsa:DisclosureOfAccountingPolicies contextRef="ctx-1" id="pp-value-20-1" xml:lang="en">AccounƟng policies Reporting Class The 2025 annual report for COMAR Engineers A/S has been prepared in accordance with the provisions of the Danish Financial Statements Act for medium-sized enterprises in reporting class B. Reporting currency translation The financial statements for the company are presented in Danish kroner (DKK). The functional currency is DKK. Transactions in foreign currencies are initially translated into the primary economic environment in which the company operates (the functional currency), applying rates approximating the exchange rates at the transaction date. Exchange rate adjustments arising due to differences between the rates at the transaction date and the rates at the payment date are recognised in financial income or financial costs in the income statement. Receivables, payables and other monetary items in foreign currencies not settled at the balance sheet date are translated at exchange rates prevailing at the balance sheet date. Exchange rate adjustments arising due to differences between the rates at the balance sheet date and the transaction date are recognised as financial income or financial costs in the income statement. Recognition and measurement Income is recognised in the income statement as earned. Costs incurred in generating the revenue for the year are recognised in the income statement, including amortisation, depreciation and impairment losses. Assets are recognised in the balance sheet when it is probable that future economic benefits will flow to the company, and the value of the asset can be measured reliably. Liabilities are recognised in the balance sheet when it is probable that future economic benefits will flow out of the company and the value of the liability can be measured reliably. On initial recognition, assets and liabilities are measured at cost. Subsequently, assets and liabilities are measured as described for each individual item below. Certain financial assets and liabilities are measured at amortised cost to achieve a constant effective interest rate over the life of the asset or liability. Amortised cost is stated as original cost less any repayments plus or minus the cumulative amortisation of any difference between cost and nominal amount. In this way, capital losses and gains are amortised over the life of the asset or liability. Recognition and measurement take into consideration anticipated losses and risks that arise before the time of presentation of the annual report and that confirm or invalidate affairs and conditions existing at the balance sheet date. Income statement Gross profit The company has decided to aggregate certain items of the income statement in accordance with the provisions of Section 32 of the Danish Financial Statements Act. Gross profit consists of external costs. External costs External costs include administrative, office, marketing as well as other costs. Other operating income and costs Other operating income and costs include items of a secondary nature compared with the company’s main activities. This includes gains or losses from disposal of non-current assets and divestment of associates. Financial income and costs Financial income and costs include interest and realised and unrealised foreign exchange gains and losses. Income tax for the year The company is jointly taxed with the consolidated entities in the COWI Group, including foreign subsidiaries of COWI Holding A/S. Income tax for the year, consists of current tax for the year, and is recognised in the income statement. Balance sheet Investment in associates Associates are all entities over which the Group has significant but not controlling influence. Investments in associates are initially recognised at cost and subsequently measured according to the equity method based on the proportionate share of the entity’s net assets. The difference between the cost and the fair value of net assets of the acquired company at the date of acquisition is considered goodwill and reflected in ‘Investment in associates’ in the balance sheet and amortised on a straight-line basis over the estimated useful life of the investment. Dividends received from associates reduce the value of the investment. Associates with negative net asset value are recognised with zero value, but if the Group has a legal or constructive obligation to cover the associate’s negative balance, a provision is recognised. Profit after tax from investments in associates is recognised as a separate line in the income statement and includes the Group’s share of profit after tax less the amortisation of goodwill. Receivables Receivables are recognised initially at fair value and subsequently measured at net realisable value, corresponding to amortised cost less provision for bad and doubtful debts. Equity The management’s proposed dividend distribution for the year is disclosed as a separate equity item. Other provisions Other provisions include the company’s legal or constructive obligation to cover the associate’s negative balance. Financial liabilities Other accounts payable are measured at amortised cost, materially corresponding to nominal value.  Current tax receivables and liabilities Current tax receivables and liabilities are recognised net in the balance sheet as tax computed on taxable income for the year adjusted for tax on taxable income for previous years. Contingent liabilities Contingent liabilities are not recognised in the balance sheet but are disclosed only in the notes. </fsa:DisclosureOfAccountingPolicies>
